Im rovernents in Music-S ool Mechanisms 'bottom i, key frame 2, findkeys 3, supported v of which the following is e specification.

The object of myv invention is to provide simple and efficientmeans tocontrol spindles or, shafts oi the music rolls in automatic musicalinstruments, to shift the shaft and roll for longitudinal adjustment asrequired.

My invention comprises novel details ot improvement and. combinations ofparte that will be more fully hereinafter set forth and then 'pointedout in the claims.

Fig 2 is a partly broken plan View, land Fig. 3 is o side View, partlyin section.

I have shown my improvements applied 1n a player pieno having' thecustomary key in the Diamo cese 4 in usuel manner, the hit-v ter beingprovided with inusic roll bon 5, e tracker 6, shafts '7,' S, tor thetakeup roll 9, shaft ylO ond adjusting device 1l 'for the music roll l2having the music sheet 13. The shaft l() is mounted to slide in bearingsin box 5 in the usual manner, end is provided with the driving sprocketlll, to bey rotated any suitable mechanism. Shaft 10 is normally engagedlo j finger i5 on e.' rock shaft lo journoled in a support l? andoperated by crank 18 in e. Well known inenner. CrsnklS is pivotallyconnected by a link 19 'with o crenlt20 on e vertically disoosed shaft 2journaled in bearings 22, 23 carried bythe pieno cose. Shaft 2l :it its{ilo'wer end is provided with s crank 2st pir# otolly connected by s rod25 with o heed or the like 26, in the nature oit` a crank, secured upone shaft 27.]ournaled in bearings 28, 29 in the key freine. The tore/ardend of shaft 27 in. front of the key freine is provided With-e' handle230 in position to be convenlently operated. To hold shavia 2f in setAposition l have shown 'n spring 3l secured to the key bottoni andbridged across on opening l therein, against which spring head or block2S hears frictionzrlly :is seid shaft is turned. Tie arrangement. ofvthe parts set forth is such that when the handle 30 is in one position,os in the vertical position shown in Fig. l, the devices that connectsaid handle with the crank 1S retain shaft 10 ine position to supportond rotate the inusic roll 12 by the interposed coupling l0n of anywell-known construction. it shaft l0 is to be adjusted in one directionor the other 'the handle will be correspondingly rocked, and by theconnections 'from said handle to crank 18, the. iinger l5 will yberocked to cause shaft l0 to be shifted the required amount to adjust themusic spool with respect to the tracker, in order to maintain .perfectregistration of the perfor-ations in the music sheet 'with the orificesin the trzrcker, and the ports will bc retained in set position byspring 3l bearing cgeinst head or block 26.
